Common knowledge of silicone rubber

Uncovering the Wonderful World of Silicone and Rubber – From Basic Knowledge to Application Fields Introduction: In modern life, we often come into contact with various materials, among which silicone and rubber are two indispensable categories. They are not only ubiquitous in daily life, but also play important roles in industries, healthcare, and other fields. This article will lead readers to explore the world of silicone and rubber in depth, understand their characteristics, classification, and wide application fields. What is silicone? Silicone is a polymer composed of silicon oxygen bonds, and its main component is silicon dioxide (SiO2). Due to the special properties of silicon, silicone has excellent high and low temperature resistance, as well as good chemical stability and biocompatibility, making it important in many industries. The types and characteristics of silicone can be divided into two categories based on the different synthesis methods: organic silicone and inorganic silicone. 1. Organic silicone: Silicone modified by organic groups typically has better elasticity, hydrophobicity, and weather resistance, making it suitable for sealing components, coatings, and other products. 2. Inorganic silica gel: Silica gel that has not undergone organic modification maintains a high porosity and therefore has strong adsorption properties. It is commonly used as a desiccant or catalyst carrier. What is rubber? Rubber is a type of polymer material with high elasticity, mainly composed of carbon atoms and hydrogen atoms. Natural rubber is processed from the juice secreted by rubber trees, while synthetic rubber can be produced from petrochemical raw materials. There are many types and characteristics of rubber, which can be divided into two categories based on their sources: natural rubber and synthetic rubber. 1. Natural rubber: It has good elasticity, wear resistance, and tear resistance, but is prone to aging and has a high cost. It is mainly used in industries such as tire manufacturing. 2. Synthetic rubber: It can be customized according to different needs and has various characteristics such as oil resistance, heat resistance, and cold resistance. It is widely used in the automotive industry, construction industry, and other fields. The difference between silicone and rubber Although both belong to polymer materials, there are significant differences in structure, properties, and applications:; Structure difference: The main chain of silicone is connected by silicon oxygen bonds, while rubber is a conjugated system connected by carbon carbon double bonds&# 8211; Different characteristics: Silicone has excellent temperature and weather resistance, suitable for extreme environments; Rubber is known for its high elasticity and wear resistance&# 8211; Different application fields: Silicone is commonly used in electronic appliances, medical devices, and other fields; Rubber is widely used in transportation, shoe materials, and other fields. Application fields of silicone and rubber 1 The application areas of silicone include but are not limited to: kitchenware, tableware, baby products, medical equipment, electronic products, automotive parts, aerospace, etc. The application areas of rubber mainly include tires, conveyor belts, shoe soles, waterproof rolls, shock absorbers, hoses, insulation layers for wires and cables, etc. Conclusion: Silicone and rubber, as two important materials, play irreplaceable roles in people’s daily lives. With the development of technology, the continuous emergence of new silicone and rubber products has brought more convenience and safety assurance to our lives. In the future, with the increasing demand for environmental protection, the research and development of green and environmentally friendly silicone and rubber products will become a new development trend.
